Chicco upended the infant car seat market with its KeyFit 30, and we are elated by the innovation of the new NextFit Convertible. For starters, there's a really cool new LATCH system with integrated pulleys that significantly reduces the effort required to tighten the install. And—get this—the seat has a whopping nine recline positions, meaning it'll fit into the contour of whatever seat you're dealing with. The NextFit is suitable from 5 to 65 pounds and has a rear-facing weight limit of 40 pounds; its height capacity is a bit more generous than other seats as well. Clever bonus: the harness width expands to accommodate wider shoulders as your child grows.
